I can't tell you from an internal perspective, but we've worked with them carrier to carrier, and found them to be quite professional and straight up in all of their dealings. As far as that FMCSA report, the miles are from 2009, as the report is for 2010. When they file their biennial update THIS fall, you will see that they are quite a bit larger now.
As for ripoff report, well, it's Ripoff Report. There are several entries for Panther on there as well, and everyone thinks they're reputable simply because they aren't a "small 2 owner operation."
The size of the operation amounts to very little in the real world. We've had to fight for checks for months on end from large, flashy companies, some of which even advertise on this site and have incredible displays at the Expo. Unfortunately, flash or no flash, they're still dirtbags. My advice is to hold out for people on here who's actually worked for them. Also ask for references from fleet owners and present owner operators, if you're feeling leery.
